Problems solved by technology

Although the analog synthesis method has a certain degree of flexibility, the method is complicated to manufacture, the synthesis efficiency is low, the synthesizer requires high technical experience, and it is not convenient for large-scale production
In addition, since the views of each viewpoint have been filtered and fitted by the software many times, their brightness and contrast have obvious loss

Embodiment Construction

[0068] The implementation process of the general synthesis method proposed in this patent will be described below through a specific embodiment of a counterclockwise prism mirror grating LCD nine-viewpoint stereoscopic display.

[0069] The 20.1-inch LCD autostereoscopic display based on the prism mirror grating used in the embodiment is precisely and tightly covered with a prism mirror plate on the 20.1-inch LCD display screen, and the prism mirror is inclined 21.5 degrees counterclockwise relative to the vertical edge of the display screen. The relevant specifications of the display screen are: the highest resolution is 1600×1200, the dot pitch is 0.255mm, the highest refresh rate is 85Hz under the maximum resolution, and the horizontal viewing angle range is 176 degrees. The pitch of the prism mirror plate is 0.6722mm, and the length of the pitch in the horizontal direction is 0.6722mm / cos21.5°=0.7225mm.

Abstract

The present invention relates to a multi-viewpoint tridimensional image synthesis method based on a raster LCD auto-stereoscopic display, which belongs to the field of raster auto-stereoscopic imaging technology. The method includes three steps; firstly, the method determines one subpixel on a LCD screen belongs to which raster unit control range; secondly, according to the arrangement of the subpixels of each raster unit, the view of each viewpoint is subsampled; thirdly, the subsampled image information of each viewpoint is arranged to compose an auto-stereoscopic display image. By the embodiment of the present invention, good synthesis effect and stereoscopic impressions can be obtained, and the subjective evaluation of several observers further verifies the validity of the universal synthesis method. The universal multi-viewpoint tridimensional image synthesis method can be widely applied to raster LCD multi-viewpoint auto-stereoscopic display devices and help to promote the industrialization of the devices.

Description

technical field [0001] The invention belongs to the technical field of grating autostereoscopic imaging, and further relates to a multi-viewpoint stereoscopic image synthesis method based on a grating LCD autostereoscopic display. Background technique [0002] Various display techniques for visualizing stereoscopic images have been developed over the years. Among these display technologies, such as prism mirror display, flat panel shielding, holographic display, etc., they can present stereoscopic images to the viewer without wearing glasses or other auxiliary visual aids. These systems are all autostereoscopic display systems. These autostereoscopic display systems can display multiple images from different viewpoints in time or space. Among many autostereoscopic display systems, the grating-based LCD autostereoscopic display device is currently a relatively common autostereoscopic display system because it is easy to process and has good multi-viewpoint stereoscopic effec...
